"There's no question, I'm going to be excited about it," Whisenhunt said on Thursday. "This is a new situation for me. I'm really excited about it."

Whisenhunt went 45-51 as head coach of the Cardinals from 2007-12. He went 8-8 in his first year and took the Cardinals to the Super Bowl a year later.

He likes what he's seen so far from his team.

"Our guys are working hard," he said. "The fans have been fantastic when I've been out and seeing people. I know it's a preseason game, and it will probably be a little bit different four weeks from now when we play the regular season, but it's fun.

"We've got so many questions that we have to get through the process of trying to answer before we pick our 53, and this is the first step. Naturally, you're going to be excited."

Titans head coach Ken Whisenhunt planned an intense practice both physically and mentally to test his players – what he didn't plan for was the heat.
